WATER HEATER.

Application filed April 29, 1920. Serial No. 377,706.

1 0 all tU/LO/It 71mg; concern:

Be it known that we, Josnrrr OSCAR SMITH and JOHN B. Rnnvns, citizens ofthe United States, residing at Los Angeles, in the county of Los Angelesand State of California, have invented new and useful Tmprovements inWater Heaters, of which the following is a specification.

This invention is a water heater and has for its object the provision ofa heater comprising a relatively long narrow flue formin g the heatingchamber and having a water jacket surrounding the same. This flue mayextend the entire height of a room and form the exhaust flue for theheater without necessitating the use of extra pipe sections. The fineforming the heating chamber being relatively narrow the greatestefficiency of the heat units passing therethrough will be expended upon.the relatively thin film of water in the narrow water jacket surr0undlugthe heating chamber, thereby causing the water to quickly heat; and thedesired capacity of the heater may be obtained by providing a relativelylong flue and water jacket.

It is a further object of the invention to provide a heater which willbe of comparativelyfew parts and which may be quickly assembled, therebypreventing the liability of the heater becoming inoperative and alsoforming an extremely cheap construction.

Further objects of the invention will be readily understood from thefollowing description of the accompanying drawings, in

which Figure 1 is a perspective view of a water heater construction inaccordance with the invention, partly broken away.

Fig. 2 is a transverse section on the line 2-2 of Fig. 1.

The improved water heater comprises a. burner chamber 1 mounted upon asupport ing standard 2 and a relatively long narrow annular water jacket3 supported upon the burner chamber and forming a combined fine andheating chamber 1 within the water jacket. Burners are provided in theburner chamber having their nozzles arranged as a Y and extendingupwardly and outwardly so as to direct the flames from the burnersupwardly through the heat chamber 4 adjacent the inner surface of waterjacket 3 so as to form a draft opening at the axis of the heat chamber.The burners are supplied with fuel from. a pipe 6.

Means are provided for automatically controlling the admission of fuelto the burners, this controlling-means forming the subject matter of ourco-pending application Serial No. 377,705, filed April 12, 1920.

The water jacket 3 is formed of con reutric inner and outer spacedshells 7 and 8 connected at their ends by cross walls 9 to provide aclosed cylindrical jacket of relatively thin width, so that acomparatively thin film of water will pass through the water jacketthereby increasing the rapid ity with which the water will be heated bythe heat from the burners passing through the heat chamber 4 inside ofthe shells forming the water acket.

The water acket is supported at its lower end upon the burner chamber 1,preferably, in an annular groove 10 provided in the upper edge of saidchamber. A second groove 11 neferably, formed in the upper edge of theburner chan'iberinside of the inner shell 7 of the water jacket, thisgroove being arranged receive any moisture which may be condensed withinthe heat chamber 4% when the burner is first started. The moisture whichmay be condensed within the heat chamber will drip from the wall ofshell 7 into the groove 11 and will be subsequently vaporized and pass Iout of the burner, thereby avoiding the dripping of water into theburner chamber.

Vvater is, preferably, supplied to the water jacket 3 through a pipe 12comnuinieating with the water jacket adjacent its lower end andextending downwardly out side of the burner chamber to a valve chamber13. A valve 14 controls the inlet of the water from a water pipe 15 intothe valve chamber and thence into the water jacket. The discharge fromthe water jacket, preferably, (ton'iprises a pipe 16 communt eating withthe )er end of the water jacket and extending inwardly from the innershell 7" and thence downwardly through the heat chamber 1. The lower endof pipe 16 is coupled to a pipe 1'? extending but wardly through theshells of the water jacket. This pipe may be connected to anysuitableconduit for the hot water. All of the connections, as thusdescribed, preferab-ly threaded connections so that the parts may bequickly assembled and taken apart. The pipe 16 extending downwardlythrough the heat chamber is, preferably, arranged concentric to theshells of the water jacket, so that all of the water passing downwardlythrough the pipe maybe acted upon by the heatwithin the heat chamber toincrease the heat of the Water. 7

A series of plates 18, preferably, surround the pipe 16 and extendradially therefrom to a point spaced slightly from the inner shell ofthe water jacket. These plates are provided with openings 19to permitthe passage ot the burning gases through the heat chamber to theupperopen end thereoflthe openings in one plate being staggered with relationto the openings in adjacent plates, thereby forming tortuous passagesforthe hot gases through the heatchamber. The plates 18 besides thusforming b'atlies for the prottlucts oi?- combustion also form heatingfins t'or'the pipe 16. Ly means of these fins the heat of the productsof combustion passiiig through the heating chamber is conducted bycontact ith'said fins directly to the pipe 16 for heating the Watertherein.

It will be observed that the waterh ater constructed in accordance Withthis invention provides a relatiyely thin Water jacket surrounding; acombined flue and heating chamber of relatively small diameter, so thataquantity i Waterin the jacket may be quickly heated, the temperature ofthis \yater being further raised during its passage through the pipe 16which is completely surrounded by the heating medium passingthrough thechamber By iii-airing the Water jacket and heating flue relatively longa relatively large amount of hot water may beobtained, and the heatingchamber also forming the flue of the burner dispenses with the necessityof employing pipe sections to term a flue.

It'willj also beobserved that the bafiles 18 are so arranged as toprevent the products of combustion passing too rapidly through theheating chamber, whereby the greatest efiiciency is obtained from theheat units 01 the heating medium, and it will be, further noted that thebafiies 18 form efiicient heat conductors to the Walls 01? the pipe 16.

Various changes may be made Without de- 'partiiig' 'froni the spirit ofthe invention as claimed.

What is claimed is:

1. A waterheater comprising aburner chamber, the top ot 'said chamberhaving an annular groove, an annularreces's forn'ied on the upperportion of the outer wall of said groove; said recess forming an annularshoulder adapted support a Water acket formed between coh centric'shellsand formfine \Vltlllll the inner shell, and the inner shell of thejacket projectin' inwardly beyond the outer" Wall of said groove andterminating intermediate the outer and inner'iyalls of said grooye.

2. A ater heater comprising "a burner chamber, the top ofsaid chamberhaving an annular groove and there being an annular recess"ioi'inecl onthe upper portion of the outer wall of said groove 'andiorming anannular shoulder, and a Water heating jacket resting-upon the shoulderseas to leave a space in said groove below the water heating-jacket andinside of the lower end of the' Wat-er heating j acket, the inner Wallof said grooye extending above the lower end of the jacket,

In testimony whereof We have signed our names to thi's specification.
